  • Protons contribute to the mass of an atom and provide a positive charge to the nucleus.
  • The number of protons determines the identity of the element.
  • Electrons have a negative charge.
  • The atom is electrically neutral, the number of electrons must equal the number of protons.

Protons are the subatomic particles which has positive charge.

The protons define the element.

So for example, every element that has 1 proton is hydrogen.

Hydrogen is a gas.

Every element that has 23 protons would be vanadium.

Vanadium is a chemical element with an atomic number 23.
